Next we fired up SiSoftware's SANDRA 2009, the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provided the results from our comparison SSDs. The benchmarks were run without formatting and both read and write performance metrics are detailed below. We also included SANDRA's graph so you are able to see how the drive performs over time and the length of the entire disk volume, along with the average rated result.

As far as SANDRA is concerned, the new OCZ Vertex 2 Pro is about as fast as the current generation of top-shelf SSDs, like Intel's X25-M or OCZ's original Vertex drive, in terms of read performance. However, from a write bandwidth perspective at 220MB+/sec, the Vertex 2 Pro drive is measurably faster than virtually all standard MLC-based SATA SSDs we've seen on the market thus far.
